Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention.
Examples
In addition, the invention also provides a using method of the tree height measuring device for the tree breast height (refer to fig. 3).
(1) And measuring the tree height.
Firstly, holding a handle 6 by a single hand, rotating an angle ruler 1 to be vertical to the ground and parallel to the handle 6, adjusting two observation mirrors 2 to be parallel, pointing a lens 21 to a tree to be measured, and turning on a laser lamp 34 of one laser ranging digital display 3; through observation mirror 2 the observation laser lamp 34 shine the position whether be located the trunk of surveying, according to actual conditions rotation angle chi 1, ensure that laser lamp 34 is big to survey the trunk on, hit digital display and open 31, digital display screen 33 with display device and the straight-line distance L between the tree.
Secondly, the observation mirrors 2 are rotated respectively through the observation mirrors 2, the observation mirror 2 at the upper position is aligned to the top end of the tree to be measured, the other observation mirror 2 moves to the bottom of the tree to be measured, and at the moment, the two observation mirrors 2 both present a certain angle (alpha)1) Calculating the side length formula according to the right triangle to obtain two lengths H1、H2The height of the tree is H1+H2The device is not limited by terrain in measurement, and a common height measuring device requires that a measurer and a tree to be measured are at the same geographical height, and measurement data are inaccurate when the heights are inconsistent.
(2) And (4) measuring the chest diameter.
The first step: determining the breast diameter position, as shown in figure 3 (different linear distances L, 1.3m height observation mirror included angle), adjusting the included angle of the observation mirror 2 according to the actual condition, aligning the lower observation mirror 2 to the root of the tree to be measured, and the position pointed by the other observation mirror 2, namely the breast diameter position (1.3m) of the tree to be measured, wherein the digital display screen 33 of the upper observation mirror 2 displays a distance L2
The second step: measuring the breast diameter, and after the position of the breast diameter is determined, rotating the angle ruler 1 to enable the angle ruler to be parallel to the ground and perpendicular to the handle 6; returning the two observation mirrors 2 to the parallel position, and then enabling the distance between the observation mirror 2 above in the first step and the measured tree to be L at the position of the angle ruler 12This position is the first step breast diameter position; observing by the observation mirror 2, moving the observation mirror 2 in parallel to make the two laser lamps 34 respectively located at the edge of the tree trunk of the tree to be measured, the distance between the two lasers is the breast diameter of the tree to be measured, and recording the included angle (alpha) of the angle ruler 12) And then, directly calculating by substituting a formula or referring to the attached figure 3 of the specification to obtain the chest diameter value of the measured tree.
Third, after the first tree is measuredMoving one observation mirror 2 to the center of the measured tree trunk, moving the other observation mirror 2 to the center of the next measured tree trunk, and recording the included angle (alpha) between the two observation mirrors 23) And the distance displayed by the second sight glass 2; and measuring and recording each subsequent tree in such a way, and finally, completing the measurement of all the target trees within 360 degrees in the sight line range to obtain the diameter at breast height, the height and the relative position of the trees.
